报告内容:
The light cone distribution amplitudes (LCDAs) give the internal structures of light mesons, are critical inputs for the description of hard exclusive reactions. The large-momentum effective theory (LaMET) allows to access the entire x-dependence of the DAs from first principle lattice calculations. In this talk, I will discuss how to derive LCDAs under the LaMET, including how to handle the divergence structures of the quasi-light-front (quasi-LF) correlators. Furthermore, LaMET gives an access to transverse-momentum-dependent(TMD) structures such as TMD parton distribution functions and TMD wave functions. Take the Collin-Soper kernel as an example, I will also give a brief introduction of how to handle these TMD structures in LaMET.
